Applications Processors: 8900B series Applications Processors: APL series
• Apple appears to have done processor designs since the iPod Touch 2nd generation released in Q3 2008 (with Samsung)
• Given that the iPod Touch and the iPhone use the same operating systems, Apple must have gained significant experience to prepare the new applications processor line by using it with the 2nd generation iPod Touch prior to launching the iPhone 3GS
• The A4 processor, an Apple designed apps processor for the iPad, has the same part numbering convention as the other apps processors since the 2nd generation iPod Touch (APL series). The iPad is also using the iPhone OS.

Summary• TechInsights has good coverage of applications processors of all
Apple handheld products: iPod Touches and iPhones.• TechInsights has been able to identify foundry of applications
processors of Apple handheld products as “Samsung” through various process analyses and tacking of every generation of Apple handheld products.
• The process technologies for applications processor identified so far includes 90nm eDRAM, 65nm, and 45nm node.
• TechInsights has detailed structure analysis report completed on all three process node parts.
• A detailed analysis on the Apple iPad Apps Processor (A4) has been started. Initial and preliminary results suggest that the A4 could be another processor with Samsung 45nm process technology. More details to follow after SEM cross sections and cross examination with the existing Samsung 45nm analysis results.
